Mathematics

Amanda [17]4 years ago

Answer:

Step-by-step explanation:

Simplifying

7x + 2y = 180

Solving

7x + 2y = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

7x + 2y + -2y = 180 + -2y

Combine like terms: 2y + -2y = 0

7x + 0 = 180 + -2y

7x = 180 + -2y

Divide each side by '7'.

x = 25.71428571 + -0.2857142857y

Simplifying

x = 25.71428571 + -0.2857142857y
